Comment:
CircleCI itself builds and distributes the CLI as `circleci` by passing the `-o circleci` flag to `go build`. Since I'm using the Go build style to run `do_build`, it won't let me pick the binary name and will simply follow the package name. Then I just rename it to follow the official distribution from CircleCI.
